While 40 frames per second might not seem like anything to get too terribly excited about, when you compare it to the 29 FPS from before the Graphics Update, it becomes clear that Valve and Apple are on to something here. That's roughly 38% quicker than Team Fortress 2 was running for Snow Leopard users a few days ago! I should also note that the gaming performance delta between Windows 7 and OS X (at least in Source-engine titles) appears to be closing dramatically, with the GeForce GT 330M hitting a similar ceiling in both operating systems. OS X users are closer to getting to blame Apple's poor GPU options, rather than poor drivers, for their gaming woes.
